In this paper, we develop a strategy to form on-demand droplets with specific pH values. The pH control is based on electrolysis of water in microfluidics, and the produced hydrogen and hydroxyl ions are separated and confined in individual containers during the droplet generation, triggered by a pressure pulse. By tuning the applied voltages and pressure pulses, we can control on demand the pH...
Background: Hypoxia-induced CA IX contributes to pH control in tumor cells, and control of pH is important for cell migration. Result: CA IX increases migration through its catalytic domain and interacts with bicarbonate transporters in lamellipodia. Conclusion: CA IX is an active component of the molecular machinery that facilitates migration of tumor cells through pH regulation at the leading...
Alteration of red blood cell (RBC) pH produces stomatocytosis (at low pH) and echinocytosis (at high pH). Cell shrinkage potentiates high pH echinocytosis, but shrinkage alone does not cause echinocytosis. Mechanisms for these shape changes have not been described. In this study, measured dependence of RBC shape on cell pH was nonlinear, with a broad pH range in which normal discoid shape was m...
